Describe strategic health care quality initiatives in two organizations attempting to accomplish their goals and objectives in quality improvement. You will also examine the purpose of the initiatives(s) and share the issues and opportunities for improvement, as well as address any elements crucial to improving quality in your health care organization or one you are familiar with.
The old adage, “form follows function” describes considering the importance of what you are trying to accomplish before you decide how to get there. It is important to remember that you have to have the will to improve, ideas about alternatives to the status quo, and make it real—execute (Nolan, 2007).
In this Discussion, you will describe strategic health care quality initiatives in two organizations attempting to accomplish their goals and objectives in quality improvement. You will also examine the purpose of the initiatives(s) and share the issues and opportunities for improvement, as well as address any elements crucial to improving quality in your health care organization or one you are familiar with.
To prepare:
Read and review the resources in the Learning Resources section as they relate to initiatives in strategic health care organizations.

Ethics in IS
People working with information systems are privy not only to sensitive information but also systems which can be vulnerable to internal or external threats. Even seemingly benign behaviors like checking personal email on a work computer can put the computer, network, and business at risk. This is why such activities are usually prohibited in the workplace or on work equipment.
From our readings and activities as well as your own experience, discuss a scenario in which unethical behavior or actions can create problems. Be specific about the risk, the issues that can result, and why it is essential to follow guidelines and ethical tenets required by an employer.
